3 Claims. (CI. 4063) This invention relates to signal casings, paronly a caution signal in which case the signal casticularly a casing for trafiic signals' embodying ing is comprised of a single section, or compartone or more signal indications. ment.

An object of the invention is a signal casing The general object of my present invention is fabricated from a plurality of parts, each of a traffic signal casing formed of complemental 5 which is complemental in form and dimensions, parts which may be readily assembled to accomwhereby the casing may be readily assembled to modate one or more signal indications. accommodate one or more signal indications. In the casing illustrated in Figure l, provision The invention has as a further object, a signal is made to accommodate tWo signal indications,

casing comprising one or more boxlike structures and comprises a pair of boxlike structures sub- 10 parallelogrammic in cross section, and each stantially square in cross section and arranged structure comprising separate side wall panels in end to end relationship. These structures are so formed as to provide an interlocked weatherformed by detachably securing together a plutight corner construction, and the bottom edges rality of separate side panels H).

In describing this invention, reference is had when assembled, the box structure or casing is to the accompanying drawings in which like provided with Weather-tight joints at the corners. characters designate corresponding parts in all To accomplish this, the panels ID are formed or the views. provided with a groove l2 extending along one Figure 1 is a side elevation showing a preferred vertical side edge of the panel, and the opposite embodiment of my invention, and being partly vertical edge I3 is so formed as to extend into in section. the groove l2 of the adjacent panel when the 30 Figure 2 is a top plan view of the casing shown panels are assembled in box formation.

That is, It is to be understood that traffic signal casings when the panels are assembled into box forma- 50 are usually provided with three signal indication, the bosses ll of one panel are arranged in -tions, namely, g0, stop and caution. However, in alinement with the threaded bosses l8 of the some instances, the caution signal is omitted, in adjacent panel, as illustrated to the right, Figwhich case the signal casing is arranged for two ure 2. During tightening of the screws I6, indications, and sometimes the signal comprises the abutments l4, because of the angular abut- 55 ting faces l5, efiect an outward movement of the edges I3 of the panels, pressing these edges panels it! are provided with a rib which overlaps the outer face of the upper edge of the panels arranged in the box structure, or section, immediately below. The opposite or upper edge of the panels I0 is provided with an upwardly extending offset flange 2| which overlaps the inner face of the bottom edges of the panels in the section above;

In addition to the box structures, or sections,

the casing includes top and bottom closures 22, 23, respectively, bell shaped in general cross section. The top and bottom closures are of similar form and construction, except that the flange or canopy 24 extends outwardly a. greater distance on the top closure than on the bottom closure, and the base of the top closure is formed to coact with the upper edges of the panels 1 il, while the base of the bottom closure is formed to coact with the bottom. edges of. the panels.

The box structure and the top and bottom closures 22, 23, are detachably secured together by rods 25 extending vertically throughout the in? side of the casing adjacent the corners thereof,

and which are provided with nuts 2s which,

when tightened, draw the sections of the casing together with the top and bottom closures together. The top and bottom closures maybe provided centrally with apertures 21 for attachment to suitable supporting means, and to pro-' vide an entrance for the electrical conductors employed in operating the signal.

It will be observed that inasmuch as the side panels ID are of complemental and uniform di- .mensions, it is only necessary to provide a stock of these panels together with the top and bottom closures, and signal, casings may be conveniently fabricated therefrom to accommodate one or more signal indications.

Where only one' box structure is used for a single indication, the

rods 25 will, of course, be shorter than those employed for a two compartment casing, and will likewise be longer for three compartment casings. 7

What I claim is:

1. A signal casing comprising top and bottom end closures, a plurality of sidewall panels, each of said side panels being formed with a groove extending along one of its vertical sides, and with spaced apart abutments adjacent each of its vertical sides, means for detachably securing said panels together, with the abutments of each panel engaging the abutments of the adjacent panels, and with one vertical side of each panel arranged in the groove of the adjacent panel to form a boxlike structure parallelogrammic in cross section, and means for detachably securing said top and" bottom closures to said structure. 7 r

2. A traffic signal casing comprising a boxlike structure parallelogrammic in cross section, said structure consisting of separate side wall panels, one vertical edge of each of said panels being formed to interlock with the vertical edge of the adjacent panel, each of said panels being provided on its inner face with spaced apart abutments arranged adjacent each vertical edge of the panel, and each panel being provided with a threaded aperture adjacent one vertical side, and an apertured boss arranged adjacent the opposite vertical edge, said abutments and bosses being arranged in alinement with those of the other panels, screws extending through said bosses and threading in said apertures to detachably secure the side panels together, top and bottom closures for said structure, and means .ior detachably" securing said closures to the structure.

3. A signal casing comprising a boxlike structure parallelogrammic in cross section, said structure consisting of separate side wall panels provided with coasting means along their vertical side edges to form an interlock between the panels, said panels being also formed with coacting abutments maintaining said panelsrin right angular relationship when secured together, means for detachably securing the panels together, top and bottom'closures, and means for detachably securing said closures to said structure.
